Could you tell me how to use Heap Snapshot Profile to detect leak？

[Liu Xiao]

Hello everyone:

Now I want to detect leak on JS heap by using Comparison View in Heap Snapshot Profile.

First I take a snapshot as a baseline.

Then I call a function in Javascript like this:

////////////////////////////////////////////////////////////////////////////////////

function create_local_array()

{

  var result = new Array(50000);

  

  for (var i = 0, l = result.length; i < l; ++i)

      result[i] = i;

}

////////////////////////////////////////////////////////////////////////////////////

At last I take the second snapshot for comparison.

But there are lots of objects new generated, so that I can't confirm if this function is good or not (no memory leak).

I think the function is good enough.

Why there are lots of objects generated？

Could you tell me how to use it to detect？
